Whakaoti i te 5(17-10^-8)/2*10^-4

$$\frac { 5 ( 17 - 10 ^ { - 8 } ) } { 2 \times 10 ^ { - 4 } }$$

Aromātai

$$\frac{1699999999}{4000}=424999.99975$$

Ngā Upane Otinga

Tātaihia te 10 mā te pū o -8, kia riro ko \frac{1}{100000000}.

$$\frac{5\left(17-\frac{1}{100000000}\right)}{2\times 10^{-4}}$$

Tangohia te \frac{1}{100000000} i te 17, ka \frac{1699999999}{100000000}.

$$\frac{5\times \frac{1699999999}{100000000}}{2\times 10^{-4}}$$

Whakareatia te 5 ki te \frac{1699999999}{100000000}, ka \frac{1699999999}{20000000}.

$$\frac{\frac{1699999999}{20000000}}{2\times 10^{-4}}$$

Tātaihia te 10 mā te pū o -4, kia riro ko \frac{1}{10000}.

$$\frac{\frac{1699999999}{20000000}}{2\times \frac{1}{10000}}$$

Whakareatia te 2 ki te \frac{1}{10000}, ka \frac{1}{5000}.

$$\frac{\frac{1699999999}{20000000}}{\frac{1}{5000}}$$

Whakawehe \frac{1699999999}{20000000} ki te \frac{1}{5000} mā te whakarea \frac{1699999999}{20000000} ki te tau huripoki o \frac{1}{5000}.

$$\frac{1699999999}{20000000}\times 5000$$

Whakareatia te \frac{1699999999}{20000000} ki te 5000, ka \frac{1699999999}{4000}.

$$\frac{1699999999}{4000}$$

Tauwehe

$$\frac{2957 \cdot 574907}{2 ^ {5} \cdot 5 ^ {3}} = 424999\frac{3999}{4000} = 424999.99975$$
